Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4 This utility model provides a technical solution:
[0025] The triboelectric electrostatic impurity removal device includes a mounting frame 1, on which a conveyor belt 13 is mounted. A processing box 2 is fixedly mounted on the downstream end of the mounting frame 1 at the conveyor belt 13. Two electrostatic rollers 24 are symmetrically mounted inside the processing box 2. A mounting plate 26 is fixedly mounted on the outer side of each electrostatic roller 24 inside the processing box 2. An electrostatic sheet 27 is fixedly mounted on the outer wall of each mounting plate 26 near the electrostatic roller 24, and the electrostatic sheet 27 is in close contact with the electrostatic roller 24. Two support frames 28 are symmetrically fixedly connected inside the processing box 2. A scraper 280 is fixedly mounted on the top of each support frame 28, and the two scrapers 280 are in close contact with the outer walls of the two electrostatic rollers 24 respectively. A feeding cylinder 210 is fixedly mounted inside the processing box 2 below the two electrostatic rollers 24, and the feeding cylinder 210 extends from the bottom of the processing box 2. This device uses friction to generate electrostatic adsorption to remove impurities from the material. Meanwhile, the processing box 2 is also equipped with a support frame 28 and a scraper 280. The scraper 280 is in close contact with the outer wall of the electrostatic roller 24 to scrape off impurities adsorbed on the electrostatic roller 24. A discharge cylinder 210 is also located at the bottom inside the processing box 2 to discharge the scraped impurities. This design enables efficient and continuous impurity removal from materials, improving production efficiency and product quality.
[0026] In a preferred embodiment, a U-shaped frame 10 is fixedly mounted on the top of the mounting frame 1, and a combing roller 11 is rotatably mounted inside the U-shaped frame 10. A combing motor 12, with its output shaft coaxially fixed to the combing roller 11, is mounted on the outer wall of the U-shaped frame 10. By fixing the U-shaped frame 10 on the top of the mounting frame 1 and rotatably mounting the combing roller 11 and the combing motor 12 inside the U-shaped frame 10, preliminary combing and dispersion of the material on the conveyor belt 13 are achieved, which helps to separate impurities from materials in the subsequent electrostatic purification process and improves the purification effect.
[0027] In a preferred embodiment, two gears 21 are mounted on the outer wall of the processing box 2, each coaxially fixed to one of the two electrostatic rollers 24. The two gears 21 mesh with each other. An L-shaped plate 20 is fixedly mounted on the outer wall of the processing box 2, and a drive motor 22 is mounted on the L-shaped plate 20. The output shaft of the drive motor 22 is coaxially fixed with one of the gears 21. By mounting two meshing gears 21 on the outer wall of the processing box 2 and using the drive motor 22 on the L-shaped plate 20 to drive one of the gears 21 to rotate, synchronous rotation of the two electrostatic rollers 24 is achieved, ensuring the stability and continuity of the impurity removal process. At the same time, this design simplifies the transmission structure and reduces equipment cost and maintenance difficulty.
[0028] In a preferred embodiment, a guide cylinder 29 is fixedly installed inside the processing box 2 below each scraper 280, with the bottom of the guide cylinder 29 extending to the outside of the processing box 2. This allows impurities scraped off by the scrapers 280 to be promptly poured out of the processing box 2, avoiding the accumulation of impurities and secondary pollution, and improving the hygiene and reliability of the equipment.
[0029] In a preferred embodiment, a lower guide plate 23 is fixedly installed below each of the two guide cylinders 29 at the bottom of the processing unit, with the lower guide plate 23 extending away from the processing box 2. This further guides impurities away from the processing box 2, facilitating impurity collection and processing, and improving the ease of use and practicality of the equipment.
[0030] In a preferred embodiment, two upper guide plates 25 are symmetrically fixedly connected to the top of the processing box 2, and both upper guide plates 25 extend between the two electrostatic rollers 24. This guides the material to enter the electrostatic rollers 24 more evenly, improving the efficiency and uniformity of electrostatic impurity removal, while also helping to avoid clogging and accumulation of material at the electrostatic rollers 24.
[0031] In a preferred embodiment, each guide cylinder 29 has a horizontal plate 211 fixedly installed inside it. The horizontal plate 211 has several equally spaced holes, and a fan 212 is installed in each hole. The airflow generated by the fan 212 can further accelerate the discharge and dispersion of impurities, thereby improving the impurity discharge efficiency of the guide cylinder 29 and the overall performance of the equipment.
[0032] In this preferred embodiment, two first legs 3 are symmetrically fixedly installed at the bottom of the mounting frame 1, and a second leg 4 is fixedly installed on each of the opposite outer walls of the processing box 2. The bottoms of the four legs are flush. This ensures the stability and balance of the equipment, facilitates its installation, debugging, and use, and also improves the aesthetics and overall coordination of the equipment.
[0033] When using the triboelectric electrostatic purification device of this utility model:
[0034] First, the material is placed on the conveyor belt 13. As the conveyor belt 13 moves, the material enters the U-shaped frame 10 at the top of the mounting frame 1. Inside the U-shaped frame 10, the combing motor 12 drives the combing roller 11 to rotate, performing preliminary combing and dispersion of the material. This helps to separate impurities from the material during the subsequent electrostatic purification process, improving the purification effect.
[0035] Next, the material enters the processing chamber 2, where it is held and passed through by two electrostatic rollers 24. A drive motor 22, mounted on the outer wall of the processing chamber 2 via an L-shaped plate 20, drives a gear 21 coaxially fixed to it. Because the two gears 21 mesh, the drive motor 22 can drive the two electrostatic rollers 24 to rotate synchronously. During the rotation of the electrostatic rollers 24, the electrostatic sheet 27 is in close contact with the rollers, generating static electricity through friction. The rollers 24 thus become charged and can adsorb impurities from the material.
[0036] When impurities accumulate to a certain level on the electrostatic roller 24, the scraper 280, which is closely attached to the outer wall of the electrostatic roller 24, will scrape off the impurities. The scraped impurities then fall into the discharge cylinder 210 or guide cylinder 29 at the bottom of the processing box 2. The bottom of the guide cylinder 29 extends to the outside of the processing box 2, which can promptly discharge the impurities scraped off by the scraper 280 from the processing box 2, avoiding the accumulation of impurities and secondary pollution. At the same time, each guide cylinder 29 is equipped with a horizontal plate 211 and a fan 212. The airflow generated by the fan 212 can further accelerate the discharge and dispersion of impurities, improving the impurity discharge efficiency of the guide cylinder 29.
[0037] In addition, the bottom of the processing box 2 is equipped with a lower guide plate 23, which can further guide impurities away from the processing box 2, making it easier to collect and process impurities. The upper guide plate 25 at the top of the processing box 2 can guide the material to enter the electrostatic rollers 24 more evenly, improving the efficiency and uniformity of electrostatic impurity removal.
[0038] Finally, the material that has undergone electrostatic purification is output from the other end of the processing tank 2, completing the entire purification process. The entire device uses static electricity generated by friction to adsorb impurities, and utilizes structures such as scraper 280, feed cylinder 210, and guide cylinder 29 to promptly remove the impurities, achieving efficient and continuous purification treatment and improving production efficiency and product quality.
[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
